A new technology harnesses imperfections that typically compromise MRI exams to create images resolved enough to enable consistent diagnoses across populations for the first time. These are findings of a study led by NYU ...

University of California, Berkeley engineers have built the first dust-sized, wireless sensors that can be implanted in the body, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles or ...

To learn what different cells do, scientists switch them on and off and observe what the effects are. There are many methods that do this, but they all have problems: too invasive, or too slow, or not precise enough. Now, ...

Fluoroscopy makes guiding a catheter through a blood vessel possible. However, fluoroscopy, a form of real-time moving X-ray, also exposes the patient to radiation. Now, a University of Missouri School of Medicine researcher ...

It's the most basic of ways to find out what something does, whether it's an unmarked circuit breaker or an unidentified gene—flip its switch and see what happens. New remote-control technology may offer biologists a powerful ...

A new technique for detecting cancer by imaging the consumption of sugar with magnetic resonance imaging (MRI) has been unveiled by UCL scientists. The breakthrough could provide a safer and simpler alternative to standard ...

Siemens has presented the world's first ultrasound system with wireless transducers. The system's transducers, which can be easily operated with one hand, transmit ultrasound images via radio waves to the screen on the base ...
